what we've all been waiting for. Our big reveal of the day, our "Gma" live event Gretta Monahan and our dream team have been hard Ott work making over pat. Let's see how he turned out. Michael, take it away. Thanks, guys. This is the moment. That was pat entering the "Gma" time machine. We said he'd lose 10 years in 60 minutes and our "Gma" dream team went one step further, style guru Gretta Monahan. Ted Gibson and Mally promised to take him from Santa Claus to James bond. Let's find out if they did it but first Sara Haines with that story. ? Reporter: It's been a smoking hot summer. Open that door. Whoo! Reporter: From 33-year-old cassie's dazzling transformation. Look at me. Reporter: To 39-year-old Amy's sparkling new style. Oh, my god. This is a dream come true for me. I don't know what to say. This is amazing. ? Reporter: Now it's time to make a little hit tri with pat roll land. Our first ever male makeover. I look at myself and I'm like, you know, this is an old man here. I need to do something to kind of match how my heart feels inside to the way I look on the outside. Reporter: The Tennessee army vet hasn't cut his hair in over a decade and says he wants help creating a sleeker younger look. Being in the military, you always had to be clean shaven. Once I got out of the army I thought, you know, it's time to let it go and I did. I let everything go. I stopped shaving my mustache and let it grow down and starting letting my hair go. Reporter: When he's out pat says people often tear at him. I don't know if it's because I'm scary-looking or old look or what. Reporter: Here to help pat, makeup artist to the stars Mally roncal, Ted Gibson and Greta hahnemann. I can't wait to lose 10 years. Reporter: For "Good morning America," Sara Haines, ABC news, New York. Once last look at pat before he entered the time machine. Now the new improved pat, Gretta, open the door. Oh. Whoa! Pat. How are you feeling, first of all? Oh, this is unbelievable. I just can't even imagine what I look like. You haven't even seen yourself. No, I haven't. Why don't you turn around and take a look in the mirror. Oh. Wow. Wow. I love it. I love it. Thanks. It looks great. You look incredible. Now, Gretta, this he say clothes make the man. I think so. So what did you do to pat? What we did, we upgraded his frame. The first thing you want to do so young up your look. The second thing, a lean suit. What makes it leaner we snuck a little man spanx in there. I think everybody should join the movement including men? Are they comfortably. Yes, they are. They're tight but comfortable. But you look good. It works. Thank you. It works for you. I can't believe it. It just is unbelievable looking. Totally be different in an hour. Hey, the dream team works fast. You should see what they do to me in 30 minutes. Machlt ally, what were you able to do. Here's the deal, first of all we talk about those brows. Any kind of landscaping we could do on it. No comment, all right. Mr. Michael, thank you but it's all about cleaning up those brows and tray hairs, pluck them, cut them, get rid of them. Men are not above makeup. You don't want to look shiny. No. Thank you very much. Are you trying to give out my secret I'm wearing a little makeup. You don't want to use the powder so I have something called the face defender which is clear and mattifies the skin and looks gorgeous. What did you do, Ted? Look how incredible he looks. You didn't say anything about the hair. It looks amazing. You know why, I think men should not have gray hair. It ages you -- we took ten years off. We shaved him and shaved him -- guys, if you have ear hair, that's a dead giveaway. You got to shave that hair. That happens? He had it on both sides growing out like a bush. Real kids in town. Aif gray hair ages you, I'm coming to see you after a show. A good guy glam moment. Enjoy your look. You are the first man to ever step into our time machine. Thank you for that. You're a real trail blazer. We want to thank Gretta, Ted and Mally. For more tips from them go to
